+--gui-dialog-file {name} *--gui-dialog-file*
+ When using the GUI, instead of showing a dialog, write the
+ title and message of the dialog to file {name}. The file is
+ careted or appended to. Only useful for testing, to avoid
+ that the test gets stuck on a dialog that can't be seen.
+ Without the GUI the argument is ignored.
